支持:Support-v4有不同的编译版本

Question

当我运行应用程序时，我会得到以下错误。

我检查了我的文件夹: C：\ Users \*。Gradle \ wrapper \ dists

我有几个版本，gradle-4.4-all，和gradle-4.1-all

他试着补充他告诉我的内容，但我仍然无法开始申请。

希望有人能帮我谢谢。

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:preDebugBuild'.
> Android dependency 'com.android.support:support-v4' has different version for the compile (26.1.0) and runtime (27.1.1) classpath. You should manually set the same version via DependencyResolution

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Answer 1

在build.gradle文件中添加以下内容( android -> build.gradle )

   subprojects {
   project.configurations.all {
       resolutionStrategy.eachDependency { details ->
           if (details.requested.group == 'com.android.support'
                   && !details.requested.name.contains('multidex') ) {
               details.useVersion "26.1.0"
           }
       }
   }
}

它应该是这样的

    buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "26.1.0"
            }
        }
    }
}

Answer 2

android > build.gradle (系统级而不是应用程序build.gradle )

subprojects {
project.configurations.all {
    resolutionStrategy.eachDependency { details ->
        if (details.requested.group == 'com.android.support'
                && !details.requested.name.contains('multidex') ) {
            details.useVersion "26.1.0"
        }
    }
}

这应该管用。多重解释https://developer.android.com/studio/build/multidex
